This invention relates to an improved method and apparatus for processing grain that will be described in relation to the preparation of grain for consumption as animal feed and also in relation to the preparation of grain to be used in products for human consumption.

More particularly this invention is concerned with an economical and eflicient method of inducing the sprouting of grain as it moves from a storage point to selective points where it can be either immediately consumed in its newly sprouted state or removed to a remote location for consumption or other uses.

It has long been known and recognized by those concerned with nutritional research that sprouted grains or seeds have substantially more nutritional value than unsprouted grains or seeds. While no attempt will be made here to define just what chemical actions and reactions take place in the sprouting of grain to produce these added nutritional values, it is recognized that vitamin and protein content of sprouted grains and seeds is considerably increased over that of their unsprouted state. For example, nutritional research indicates that 100 grams of whole dry oats contain 11 mg. of vitamin C before sprouting and mg. after germinating for 96 hours. This is increased to 42 mg. at 120 hours. Dry peas contain zero mgs. of vitamin C before germinating and 86 mg. after 96 hours of germination. Other vitamins have similar characteristics of which the following exam ples are illustrative: Thiamin (AB) increases from 7 parts to 9 parts in wheat; Riboflavin (B') increases 4 parts; Niacin, Pantothenic Acid, Pyridoxine and Biotin (B doubled; and B wheat seed increased from 28 parts to 106 parts. Other vitamins show similar increases.

The use of sprouted grain for both animal and human consumption has been attempted on a very limited scale both in this and foreign countries and while the results from a nutritional standpoint are exceedingly favorable, the high cost of adequate methods and equipment for producing sprouted grain has made it impractical to economically employ such processes to any wide extent. Consequently, in view of such high costs, present commercial feeding practices in relation to animals, for example, utilize only the unsprouted grain and seeds which do not remain in the digestive system long enough to develop and release all of the nutritional elements which are potentially present, and, as a result, the feeding period for developing desirable weights and meat quality in cattle, for example, may run from 9 to 12 months with relative high feed costs per pound of gain. However, it will be appreciated that while an extended period of feeding unsprouted grain may eventually bring weights up to specified limits, still the full nutritional potential of the grain is never developed under present feeding methods because the grain is consumed in unsprouted form.

With the above observations in mind, extensive tests have been conducted in the feeding of sprouted grain to cattle and hogs, for example, with no protein concentrates, antibiotics or other additives being used. The animals used in such tests maintained an excellent state of health during the tests and the production of red, rich muscle protein and adequate, but not excess, fat was produced in approximately one third the time usually required under present feeding practices and at considerably less cost per pound of gain since the superior nu- 3,339,529 Patented Sept. 5, 1967 tritional value of the sprouted grain required a lesser amount of feed consumption to reach a given weight limit than in the case of unsprouted grain feed. Such tests also determined that a prime grade of meat could be produced at lesser total weight than heretofore was considered possible. In relation to hogs, such tests showed that the carcass weight produced over 30% less lard than with hogs on unsprouted grain feed which means more lean meat and less lard. Other results noted include the facts that manure from animals fed on sprouted grain had no objectional odor; that such animals were more quiet and gentle and appeared to be bothered little, if at all, from flies and insects.

The above noted tests merely confirmed the fact that results from a feeding program utilizing sprouted grain are far superior to any results obtainable under present feeding programs and accordingly, one of the important objects contemplated herein is the provision of an economical and commercially practicable method of inducing the sprouting of grain for use in an animal feeding program, together with novel apparatus for use therewith.

Another object inhering in this invention is to provide for the sprouting of grain for feed purposes which can be consumed at the point of processing or which can be delivered to a point of deposit for removal to a remote location for consumption or other uses.

Still another object herein is to provide an economical means for sprouting grain that is to be used for purposes of human consumption.

More particularly, it is an object here to move unsprouted grain from a point of storage to a point of use and during such movement to not only saturate such grain with water from a controlled reservoir supply at a controlled temperature but to continually re-saturate such grain with the same water so that nutritional elements in the water are not lost.

A further object in relation to an animal feeding program is to utilize the water referred to above as a source of drinking water for the animals being fed so that they will obtain all nutritional benefits therefrom.

Still another object herein is the provision of a controlled recirculated water supply which, in the animal feed program, utilizes the water in which saliva drippings from the animals fall for circulation through the grain during processing.

Yetanother object is to provide for the water saturation of grain as above indicated either on a predetermined timed cycle basis or in response to thermal and moisture sensing means set to predetermined requirements.

A further object herein is the provision of an animal feeder that can be adapted easily for use by cattle or hogs and which may also be adapted if desired for feeding poultry.

To attain these objects and such further objects as may appear herein, or be hereinafter pointed out, we make reference to the accompanying drawings forming a part hereof, in which:

Referring to the drawings, and more particularly at this time to FIGS. 1-7 inclusive, an animal feeder is designated generally by the numeral 20 and is shown to illustrate that form of this invention where grain is processed from its unsprouted to sprouted state for consumption by the animals, such as cattle and hogs, for example, at the site of the feeder. The more or less house or hutlike appearance of feeder 20 is basically of a design that is not uncommon and while no invention is claimed in certain of the structural features per se, we have adapted many changes and improvements as will become apparent and be pointed out as this description proceeds.

Feeder 20 for purposes of reference includes a front end 22 (FIG. 2), a rear end 24 (FIG. 1) and the respective opposed sides or

side areas

26 and 28.

Side areas

26 and 28, as will become apparent, are similarly constructed so as to utilize feeder 20 for feeding purposes at two places and in this regard, the grain processing apparatus is merely duplicated for each side. It will thus be appreciated that a detailed description of this invention in relation to only one feeding side will suflice for both sides and thus in the following description aside from the general basic construction of feeder 20, reference is made to side 26 and corresponding parts for side 28 will be given like numerals primed.

Feeder 20 includes a :base floor or platform 30 which carries suitable corner posts 32 that in turn support studding 34 to which there are attached the rafters 36 of the gabled roof 38. The side edges of roof 38 over hangs the

side areas

26 and 28 to provide weather protection as will appear and additional studding 40 to such overhanging portions may be provided in any well known form as best seen in FIG. 4. Lights 41 may also be provided under the overhang of roof 40 (FIG. 4) for obvious reasons. The

sides

26 and 28 are enclosed by the relatively low

upstanding walls

42, 42 and ends 22 and 24 are likewise enclosed by siding or the like 44 and 46 (FIGS. 1 and 2). Spaced above base 30 and parallel thereto but :below the top plane of

walls

42, 42 is the floor 48, 48' which provides an equipment chamber or compartment 50 below.

Floor sections 48, 48' are separated by an inverted V shaped deflector member 52 which extends between the rear end 24 and a partition wall 54 near front end 22 and which has its apex point or ridge 56 somewhat higher than the top of

walls

42, 42. Wall 54 together with side wall 42, 42', floor 48, 48', and the rear wall 46 thus provides the feeding troughs 58, 58' and further defines the forward compartment or vestibule 60 (FIG. 6) to which access is provided by the door 62 (FIG. 2) and which may be lighted as at 63 (FIG. 5

The interior of feeder 20 is divided longitudinally by a partition 64 supported on the ridge 56 of deflector 52 (FIG. 4) and extends upwardly to point 66 that is preferably spaced below the apex 68 of roof 38. End portions of partition 64 are braced by the beams 70, 70' connected to the respective posts 34 and such partition thus provide two grain storage compartments or

hoppers

72, 72 which are completed by the sides 74, 74' that extend from the rafter 36 at point 76, 76' downwardly and inwardly to point 78, 78' which is below the plane of ridge 56 but spaced above the top of

sides

42, 42 that define the top of the

feed troughs

58, 58. Inclined posts or

studs

80, 80 may also be used for support of walls 74, 74' as best seen in FIG. 4.

A door or hatch 82 is provided in roof 38 for grain 4 access and a second door 84 (FIG. 1) is provided in the upper portion of the rear wall 46 in a well known manner. The construction of feeder 20 so far described, with the exception of the vestibule 60 and compartment 50 is generally one of a well known design adapted to provide a grain storage bin or hopper for gravity flow through the restricted

passageways

86, 86 between the bottoms 78, 78' of

walls

74, 74 and the sloping side of the deflector board 52 that directs the grain to the respective feed troughs 58, 58'. Between passageways 86, 86' vertically adjustable barriers 87, 87 may also be provided in a well known manner to limit the flow of grain from the processing area into the feed troughs 58, 58'.

It will be appreciated so far that hoppers 72, 72' and their

related troughs

58, 58 are merely duplicate constructions which obviously permit the feeding of more animals than a single trough, or the feeding of different feeds and since the processing apparatus to be described is also merely duplicated for each hopper, further description will be directed to bin or hopper 72 and like numerals for like parts in hopper 72' will be primed in the drawings only except where specific reference to the primed part seems expedient.

A means for regulating the flow of grain through passageway 86 is provided by means of the inverted V board or deflector 88 which is vertically movable in the lower portion of hopper 72. Opposed edges at each end of deflector 88 carry rollers 90 (FIG. 7) which ride in grooves 92 formed in opposed vertically arranged posts 94. A control rod 96 secured to each apex and of deflector 88 extends through the rear wall 46 and partition 54 where its free end is bent upwardly and threaded for vertical adjustment in a bracket 98 with a nut 100. By this arrangement, further restricted

grain passageways

102 and 103 are provided between the respective edges of the V board 88 and the hopper walls defined :by wall 74 and deflector side 52 to control the amount of grain moving toward passageway 86. Consequently, as V board 88 is raised or lowered, the size of

passageways

102 and 103 are increased and decreased accordingly and in addition to this function, board 88 serves to effectively partition hopper 72 so that that portion of the hopper above board 88 is a storage area or reserve chamber and that portion below board 88 between

passageways

102 and 103 and 86 is what we shall refer to as the processing area or chamber for reasons that will become apparent as this description proceeds. Means are provided to ventilate each processing area if desired or necessary and this includes an exhaust fan 104 in the rear wall 46 at the level of the processing area and an oppositely disposed louvre or screened openmg 105 in the partition wall 54. A closa'ble peep hole 106 is also provided in the rear wall 46 for visual observation of the processing area described.

A water tank or reservoir 107 which serves as the central source of water supply in the grain sprouting process to be hereinafter described is located in compartment 50 in any suitable place but preferably near vestibule 60 for easy access to the parts thereof and in the case of double feeding areas such as

troughs

58, 58, it is convenient to locate tank 107 approximately below partition 64. The size of tank 107 will, of course, vary with the size of feeder 20 and the number of animals to be fed, or in the case where there is no feeding at the site, as will later appear, in accordance with the amount of grain to be processed Within given time periods. Water 108 is deliwered to tank 107 by a supply line 110 which will connect to any suitable source of supply under ordinary main pressure and a desired water level is maintained in tank 107 by a float value 112. A manual valve 114 may also be placed in line 110 if desired as seen in FIG. 3.

Water 108 is preferably maintained at 75 F. by any suitable type of heating element 116 that is responsive to a thermal element 118. We have used a gas heating unit 120 with a control knob 122 for element 118 but any other form of heater may be employed. Heater 120 is provided with the usual vent stack 124 that extends upwardly in vestibule 60 through the roof 38. The temperature of water 108 may be permitted to vary from 75 F. but it is pointed out that the possibilities for undesirable results are substantially increased if such temperature exceeds 120 F. or fall below 37 F.

Water 108 under certain temperature and moisture control means is used to moisten feed or grain moving through the processing area below the V board 88 and is also used for drinking water for the animals and for this purpose a water pumping and distributing system is used as will be described with reference being made more particularly to FIGS. 3, 5, 6 and 17. It should first be mentioned that while partition 54 defines the front end of the feeding through 58, the trough structure actually extends forwardly thereof so that partition 54 also in effect divides the trough into the feed retaining portion 58 previously described and a drinking compartment 126 adjacent the forward end 22 of house 20. Trough 58 and compartment 126 are connected for water flow communication in any suitable manner that will keep feed 128- in the trough 58 and this may be by means of a screened opening 130 (FIG. 6).

For purpose of our water control system, a pump 132 operated by an electric motor 134 is mounted on floor- 30 Within compartment 50 (FIGS. 5 and 6') with pump 132 connected to tank 107 by pipe 136 and arranged so that water 108 drawn from tank 107 passes through a filter unit 138 which is located in tank 107 near the surface level of the water 108 as best seen in FIG. 18 whereby the water to be circulated through the processing area is drawn from the top of the water supply which is warmer than the lower portion. This is preferably done because there are temperature variations in tank 107 which are conducive to the growth and multiplication of whatever elements may be in the tank and such elements can seek their own temperature range which enhance their value for nutritional purposes or otherwise. From tank 107, water 108, when pump 132 is actuated as will later be referred to, flows through pipe 140 to a manifold 142 having a pair of outlets each normally closed by the respective solenoid operated

valves

144 and 146. A water pressure release valve 148 is imposed in line 140 between pump 132 and the manifold 142 for obvious reasons. Valve 144 is connected by a flexible flow line 150 to a sprinkle pipe 152 that is secured to the underside of the apex of V board 88 as best seen in FIGS. 4 and 6 and the flexibility of line 150 permits it to be moved with any vertical adjustment of board 88 that may be desired. Valve 146 connects to a filler pipe 154 that is arranged to supply water 108 direct from tank 107 to the drinking compartment 126. A filtered overflow pipe 156 extends from compartment 126 to tank 107 (FIG. 17).

Certain controls for the water system so far described are provided and these will be described in reference more particularly to FIGS. 5 and 17. For purpose of supplying the heated water 108 to grain 128 in the processing area, a temperature sensitive probe 158 and a moisture sensitive probe 160 and suitably suspended in the processing area and are connected in parallel through leads 1'62 and 164 so that when either probe responds to the limits of temperature or moisture as predetermined, valve 144 will be opened by the closing of switch 166 and pump 132 will be actuated to supply water to the sprinkle pipe 152 by the closing of switch 168. In this regard (FIG. 17) it will be noted that pump 1'32 and motor 134 operate on V for which the circuit is shown in heavy lines, and probes 158 and by means of a transformer 170, operate on 24V for which the circuit is shown in light lines.

In the drinking compartment 126 a float actuated switch 172 and a temperature sensitive probe -174 are connected in parallel through

leads

176 and 178 so that when either one responds to its prefixed requirements, valve 146 is opened by the closing of switch 180 and pump 132 is actuated to supply water to the fill pipe 154 by the closing of switch 168. Control dials 182, 184 and 186 are operatively connected to the

respective sensing elements

158, 160 and 174 and are mounted to partition 54 within the vestibule 60 as seen in FIG. 5.

OPERATION With the grain processing and feeder device constructed as described, it will operate in the following manner. Grain 128 to be processed from an unsprouted to sprouted state is supplied to the storage area or chamber within hopper 72 and the V board '88 is adjusted so that

passageways

102 and 103 permit the grain to pass from the storage area to the processing area at the desired rate. It will be understood that water 108 is maintained automatically by float valve 112 at a desired level in tank 107 and is also automatically maintained at preferably 75 F. by the thermostatically controlled heater 120. Board 88 by being inverted not only provides an air space for ventilation by fan 104 within the processing chamber, but also protects the grain in the storage area from spray from pipe 152.

The grain or feed 128 is induced to sprout or germinate under proper conditions of moisture and temperature as is well known and heated water 108 from tank 107 is sprayed over the grain in the processing area either in response to moisture or temperature requirements as called for by

probes

158 and 160 from time to time. The grain, in the device so far described, moves by gravity from the processing area into the feed trough 58 and initially this movement may be prevented by barrier 87 for a predetermined length of time while the grain is germinating. Such time interval can be determined by experience with different grains and once the sprouting process has commenced, barrier 87 can be opened to permit the regulated flow of grain to the fed trough 58.

As grain in the processing area is sprayed from time to time, the residue water filters into trough 58 with the grain and also accumulates in the drinking compartment 126 in which there is no feed because of screen 130. Thus, as the animals feed, they not only obtain water from trough 58 which is mixed with the feed, but they can also drink from compartment 126. As this occurs, their saliva drippings are co-mingled with the water in trough 58 and compartment 126 and this eventually finds its way back to tank 107 through the overflow pipe 156 where it becomes -a part of the central water supply in tank 107 which is admixed therewith and generally agitated by the pressure of fresh water entering tank 107 through line 110 and is eventually sprayed on the grain in the processing area.

The level of water in compartment 126 is regulated by float valve 172 so that it is sutficiently below the bottom of barrier 87 (FIG. 4) to permit free movement of the grain through passageway 86 into trough 58 and to expose passageway 86 to the atmosphere for necessary aeration and when valve 172 calls for water, the same is pumped directly from tank 107 through pipe 154, it being understood that such water includes water that has passed through the grain and returned to tank 107 through pipe 156. Also in compartment 126 is the heat sensing element 174 that is preset to a temperature somewhat lower than that of the water in tank 107. However, compartment 126 is exposed to the atmosphere and it is desired that the trough and drinking water not be permitted to freeze and that it be kept at suitable drinking temperatures. Thus, element 174 will call for water at prefixed temperature and even though compartment 126 may have an adequate supply as far as valve 172 is concerned, warm water from tank 107 will be pumped through pipe 156 until the water is at a desired temperature and the overflow pipe 156 will return excess capacity to tank 107.

The trough 58 and drinking compartment 126 are at proper heights for use by cattle but for use by hogs, for example, we have provided a ram 188 to a feeding platform 190 at the reqiured height. This is a removable structure being attachable to house 20 by suitable catches 192, and gate members 194 for the respective ends of platform 190, when used, are hingedly attached to the house 20 (FIGS. 1 and 2). Such gates 194 are secured to platform 192 by a bolt means 196 when in use and such bolt is also used to hold the gate in folded position when not used as seen in FIG. 2.

In the operation of this device as described, it is pointed out that the time intervals for spraying the grain in the processing area may be regulated on a fixed interval basis by a time clock device as well as by temperature and moisture sensing means and as a matter of expediency, such control means is illustrated in certain modified structures as will later appear.

MODIFIED STRUCTURES Because it is contemplated that grain sprouted by the process described above may be used for further processing into human foods or may be processed as animal feeds to be consumed at a remote location, we have shown certain modifications in apparatus to accommodate these dilferent purposes. Consequently, where like parts are present, like numerals for such parts already described will be used.

The first modification is shown in FIGS. 8-12 where the grain processing unit is enclosed in any suitable structure such as the rectangular building or house 198 which includes the floor 200,

sides

202, 204, front and

rear walls

206 and 208, front door 210 and roof 212 in which there is the hatch 214. A partition wall 54 defines a vestibule 60 as previously described and elevated beams 216 at the front and rear extend between

walls

202 and 204 as seen in FIGS. and 11. Above beams 216, hopperlike sides 218 define the grain storage area 220 and below beams 216, other hopper-like sides 222 define the grain processing area 224. At the lower discharge end of the storage area 220 there is provided a plurality of longitudinally spaced grain discharge openings 226 (FIG. 9) closeable by respective sliding gates 228 that are all connected to a movable rod 230 which is operable by a lever means 232 mounted to wall 54 within vestibule 60 whereby the size of openings 226 can be selectively varied. Immediately adjacent and below openings 226 is the auger-like slinger or diffuser 234 operated by the electric motor 236 having the manual switch 238. At the bottom of the processing area 224 a suitable conveying means here shown as an auger 240 is operated by motor 242 for moving the processed grain through the rear wall 208 to the directionally adjustable conveyor 244 operated by motor 246. Conveyor 244 includes a dispensing spout 248 in a well known manner. The water distributing system for the device shown in FIGS. 8-12 is similar to that previously described except that that portion of the system associated with the feed trough 58 and drinking compartment 126 has been eliminated. However, it will be noted in FIG. 9 that auger 240 slopes slightly downwardly from the rear to front of house 198 and near its forward or lower portion it is provided with an opening 250 covered by screen 252 so that residue water which has passed through the grain can drain into tank 107 for re-use.

In FIG. 11, the

probes

158 and 160 are shown which function as described above and in FIG. 10, for illustration, a time clock device 254 is illustrated whereby the operation of pump 132 can be set on a time schedule if desired. It is also noted in the variation of FIGS. 8-12 and particularly FIG. 10 that the flexible water line in FIG. 5 is replaced by rigid conduits 256 connected to a Y fitting 258 in line 140. The two lines 256 are used because two sprinkler pipes 152 are preferably employed with this modification.

A second modified structure is shown in FIGS. 13-16 where the outer structure is similar to that in FIGS. 8-12 and like parts are given like numerals. Actually, this arrangement is merely a combination of those previously described where it will be seen that the V board structure of FIG. 4 is used to separate the storage area from the processing area and the conveyor means 240 in FIG. 9 is used to move the grain out of the processing area. The water system is the same as described for FIGS. 1-7 except for the elimination of the trough 58 and drinking compartment 126 and like numerals appear on like elements. In FIGURES 15 and 16 it will be noted that both the thermal and moisture sensing controls 158 and 160 as well as the time clocks control 254 for the water system are shown since both may be installed for use as desired.

The third modification illustrated in FIGS. 18 and 19 embodies the same water distributing system as shown in FIGS. 1-7 and also the same building structure with the exception of the elimination of barrier 87 as seen in FIG. 4 and the substitution therefor of an elongated paddle wheel 260 disposed in passageway 86 with such passageway being narrower than shown in FIG. 4 by extending the bottom 78 of hopper side 74 closer to the deflector board 52 as best seen in FIG. 19. Wheel 260 is journalled between partition wall 54 and the rear wall 24 of house 20 and is operated by means of an adjustable speed motor 262 as seen in FIG. 18. Wheel 260 alfords a positive feed control means which permits the feed to be supplied to the trough 58 at selected intervals. In this regard, the grain may be held within the processing chamber until the sprouts are of a desired length as wheel 260 serves also as a closure for passageway 86 when not in operation.

As pointed out earlier, the quality of the meat on animals fed with grain processed as disclosed herein has been vastly superior to that of animals fed on unsprouted grain and the time interval required to obtain this quality has been reduced approximately two-thirds over present feeding methods. It has also been observed that when this process is initially started with a supply of grain the germination period is of a longer duration and that germination appears to progressively increase as water that has passed through the grain is returned to tank 107 for reheating and recirculation. While we are not prepared to explain the reason for this acceleration in germination by re-using the water as described, it would appear that such water absorbs an accumulation of unknown entities that are a part of the germination process which develops the full nutritional potential of .the grain and the re-use of the water so afiected materially increases the sprouting growth. It has also been observed that animals fed on this process obtain all of their drinking water from either trough 58 or compartment 126 and do not seek water elsewhere.

Also, for some reason not readily understood at this time, animals fed on the process described produce manure which has no objectional odor and also such animals appear to be bothered little, if at all, from flies and insects while other animals nearby on conventional feed had the usual accumulation of flies and manure odor.

The results indicated are believed to be directly related to the nutritional advantages of sprouted grain, and the process and apparatus described for inducing such sprouting has been demonstrated as a most efiicient and economical way for accomplishing the objectives intended.

It is submitted that the invention shown and described is aptly suited to achieve the purposes intended and is characterized by a combination of highly useful and mutually cooperating elements that combine their respective and proportionate functions in accomplishing the objects sought to be obtained.

It will be understood that the phraseology employed herein is for the purpose of description and not for limitation and that modifications and changes can be made within the scope of what is claimed, without departing from the spirit and purpose thereof.
